Abstract:
This pilot study describes a relationship between insulin resistance and micro-opioid neurotransmission in limbic appetite and mood-regulating regions in women with polycystic ovary syndrome (PCOS), suggesting that insulin-opioid interactions may contribute to behavioral and reproductive pathologies of PCOS. We found that [1] patients with PCOS who are insulin-resistant (n = 7) had greater limbic micro-opioid receptor availability (nondisplaceable binding potential) than controls (n = 5); [2] receptor availability was correlated with severity of insulin resistance; and [3] receptor availability normalized after insulin-regulating treatment.
